Answer: 3t²(2st⁷ - s⁶ - 2t⁵)
<u>Step-by-step explanation:</u>
5s⁶t² + 6st⁹ - 8s⁶t² - 6t⁷ <em>5s⁶t² and - 8s⁶t² are like terms which = -3s⁶t² when combined</em>
= 6st⁹ - 3s⁶t² - 6t⁷ <em>next, factor out the GCF of 3t²</em>
= 3t²(2st⁷ - s⁶ - 2t⁵)
Answer:
The choice 210
Step-by-step explanation:
![3{[3(9 - 2)] +[7(8 - 1)] }\\ 3[3(7) + 7(7)] \\ 3[21 + 49] \\ 3[70] \\ = 210](https://tex.z-dn.net/?f=3%7B%5B3%289%20-%202%29%5D%20%2B%5B7%288%20-%201%29%5D%20%7D%5C%5C%203%5B3%287%29%20%2B%207%287%29%5D%20%5C%5C%203%5B21%20%2B%2049%5D%20%5C%5C%203%5B70%5D%20%5C%5C%20%20%3D%20210)

The answer is 20 ,80-60=20
Answer:a+b ≥40
5+a≤ b
2.50a+1.50b≤ 105
i believe
Step-by-step explanation:
The equations would be:
a+b ≥40 (cupcakes +cookies must be at least 40 total)
5+a≤ b
(At most 5 more cupcakes then cookies)
2.50a+1.50b≤ 105
(The cost of cookies and cupcakes must be less than $105)
